A printing mail processing apparatus has an apparatus housing with a cassette bay therein, for removably receiving an exchangeable cassette. The cassette bay is closed by a cassette flap that has a finger on an underside thereof that interacts with a sensor. The sensor can detect, before exchange of a cassette that flap position for which a cassette extraction is possible. A microprocessor is connected to the sensor and uses the signal from the sensor to detect the position of the cassette flap. Given a closed cassette flap, the microprocessor causes voltage to be supplied to a chip reader unit mounted in the cassette bay. Given an opened cassette flap, the microprocessor causes voltage to be disconnected from the chip reader unit before each cassette exchange.
